Optical Sensors use light to affect a signal, either by detecting light radiation, infrared radiation, or laser beams. Photointerrupters use a light emitting diode (LED) and a photosensor to detect an opaque object moving through an air gap in an assembly. Slot Type Photointerrupters detect objects in motion by sensing blockage of a light beam passing through a slot or opening. Logic Output Photointerrupters are used in applications such as factory automation, sensing a gear on a motor shaft, or the presence of a piece of paper in a printing machine. The OBP695AZ is one such device.

The OBP695AZ is a Logic Output Photointerrupter that is a high-sensitivity, low-signal input component. The OBP695AZ is housed in a compact 3 pin package, making it ideal for low profile sensor designs. The device is rated for operation over an extended temperature range of -40 to 85 ºC. The OBP695AZ’s slots are configured such that the output will switch between high and low logic states when an opaque object blocks the beam of light. The status of the logic output can be viewed with an oscilloscope or other logic-monitoring tool. The OBP695AZ is designed to optimize response time and switching speed, making it suitable for fast-moving objects.

The OBP695AZ consists of a light source, such as an LED or a laser, and a photosensor, such as a photodiode, phototransistor or a CCD. The photosensor is typically placed directly opposite the light source. The device’s internal circuitry monitors the light source and photosensor. When the light source is blocked, the internal circuitry will detect the change and output a logic signal indicating that the light source is blocked. The device’s logic output can be either an open-collector transistor or a CMOS output.

The OBP695AZ is suitable for applications such as paper and machine sensing, object detection, and industrial automation. In paper sensing applications, the OBP695AZ is used to detect the presence of a piece of paper in order to stop the printing process. In machine sensing, the device can be used to sense the presence of a gear on a motor shaft, or to check the alignment of machine parts. In industrial automation applications, the device can be used to control the movement of motors and servomotors, as well as to detect fault conditions.

The OBP695AZ is a robust, easy-to-use device with fast response time. It requires minimal external components, making it an ideal choice for low profile sensor designs. The device is backed by a strong warranty, ensuring that it provides reliable and consistent operation. The OBP695AZ is a reliable, accurate and economical solution for a wide range of sensing applications.
